MK5 GTI - Intercooler Hoses leaking again. Replacement suggestions please.

(1/4) > >>

GreigC:
Today I had the car serviced and hand-break cables replaced. My mechanic said my intercooler pipes are leaking again (only the drivers side) I’ve changed all the O-Rings twice now on both cooler pipes over the last 18months. I bought all Genuine seals and replaced the correct part numbers to the correct sides as one side is bigger than the other… I want to change both intercooler pipes and keep the original OEM intercooler. If I buy genuine I believe there is a cross over in part numbers depending on year. My Car is 2009 MK5 GTI. I would also consider aftermarket if recommended.

Thanks

Fit the S3 / Mk6 R intercooler which is larger and does away with those leaky joints. Loads of info online and did it to mine.

ZoliWorks:
Yeah, straight up replace your mk5 intercooler with the next one. No matter what you do, those quick connections are going to leak regardless.

GreigC:
So if I remove the MK5 cooler and get a MK6 cooler from an R or 8P S3 cooler what about the hoses.. what’s involved with those?

mjmallia:
Use original hoses, but the cooler ends need the metal outer ring cut (carfully) and removed to create a simple hose connection.

Add a hose clamp and you are done.
